Can't change display sleep time

[bbfugitive]

My new T-mobile Z981 is having the same issue as reported in http://androidforums.com/threads/cant-change-display-sleep-time.1051649/. I only have the option for 15 seconds in the Settings/Display/Sleep menu.

Anyone hear of this issue?

Easy fix. Go to security and change your "automatically lock" to a different time. If you change it to 2 mins you go back and can change the display sleep time to 15,30 1 min and 2 mins

I have tried this "fix" to no avail. I just had to replace the one I got back in July due to overheating and battery issues, now this one no matter what setting I have the sleep and lock screen set to it turns off 30 seconds at most. Makes playing games, reading Facebook, and reading emails and newsletters for work really difficult.

I just had this same problem I couldn't get my screen to stay on for more than 30 seconds so I did these two steps and now my phone stays on for 2 minutes.

1st go to "SECURITY" in ur settings then click on "SCREEN LOCK" and click on the lil green gear on the right hand side of the word then click on "AUTOMATICALLY LOCK" and pick the mins u want.
"THEN"
2nd go to "DISPLAY" click on it then click on "SLEEP" and select the mins u clicked on when u did the 1st steps.

If you really want the correct answer, and the previous answers have not worked, then hears the correct answer

Turn off battery saver,

I was looking here for the same reason, display timed out at 30sec and I couldn't change it, it was blanked out, I tried the above solutions which didn't work ! Then I noticed that battery saver was on, so I turned it off, and then was able to change the the sleep screen time out, which had already automatically turned back to 2 mins anyway

That might not be sleep settings that might be light sencer settings
